Ice Universe talked about the Samsung Galaxy S26 Ultra\u2019s Privacy Display tech in the past, but he just went into more details. He shared a \u2018Deep Dive\u2019 post via X, explaining exactly how this tech will work. Do note that he provided an extremely technical explanation, so read on if you\u2019re interested.<\/p>\n

The light passes freely until you enable Privacy Mode<\/h2>\n

He says that the first security gate is Micro \u2018Louvers\u201d (bottom grating). The light emitted by the OLED screen originally scatters in all directions. Before you enable Privacy Display, the first security gate is completely invisible. Why? Because the refractive indices across all layers are exactly the same. All light passes freely, basically.<\/p>\n

After you enable Privacy Mode aka Privacy Display (voltage on), the liquid crystal layer instantly changes state. That causes a shift in its refractive index. At that moment, the microscopic grating (Diffraction Structure), which is carved into the surface of the first refractive layer, reveals itself. It acts as a series of microscopic \u201clouvers,\u201d says the tipster.<\/p>\n

Those light rays that are trying to escape at wide angles to the left and right are forced to change their path as they pass through these louvers, which deviate from their original trajectory.<\/p>\n

The second security gate decides the life or death of the light emitted by the display<\/h2>\n

The second security gate is Optical \u201cRefraction Slopes\u201d (top prism\/lens). The light rays, which have had their path scrambled by the first gate, crash into the optical structure (prism or lens) at the top of the refractive index conversion layer. The tipster says that \u201cthis is where the life or death of the light is decided.\u201d<\/p>\n

Those wide-angle light rays originally destined for the snooper\u2019s eyes hit the prism slopes at extremely awkward angles, it is said. Why? Because there is now a refractive index difference between the liquid crystals and the top refractive layer. That portion…<\/p>\n
